Be it known that l, HOMER-A. Woons, .a citizen ofthe United I States, residing at In-- dianapolis, in the c'ountyof Marion and State of Indiana, have inventedanew-and useful E'gg-Gandl'ing Attachment for Port able Lanterns, of whichthe following is-a= specification. V

It is the object of my invention to provide a simple and inexpensivefeg -candling device for 1 attachment to portable "lanterns;

the egg is being tested," the connection -bei: M

ing made by theegg it self-as it isput in testing position, and whlch lw ill' 'be properly connected when-attached to the'lantern even by 'a *novice.- The accomp anyingdraw-ingsllustrate my invention. Figure 1 is a.- plan view of a lan tern with 'iny egg-candling attachment;

egg-candling attachment, with the sight tube broken away Fig. 5 is a partial rear view of such egg-candlingattachment, Wlth,

largedsection on the line 6-6 of Fig.4; Fig. 7 is a section on the line 7-7 of Fig.

i; and Fig. 8 isa section-on the line 88- The portable lampcomprises' a casing 10' with a rear carrying handle-11' and; a carry ing bail 12-, and is provided with a removable top 13. On the front of thef casing ltl is mounted a reflector in arefiector housing '14 the end of which is screw-threaded, and

18 of thecell 17 and the carbon bindingpost' 19 of the 'cel1' 16. There is also a control switch 20 which is mounted on therear of the lanternsothat its operating handle can be operated by the thumb of the hand grasp ing the handle 11. I Thenormalconnections of this switch :are between the .zinc binding lamp. l5.

iWIyf egg-candling attachment is mounted on the-forward end-of the reflecto-r housing 14, :andcomprisesascreW-tln'eadedj cupshaped member 25 (Fig. 6) WhiQh'IDZLY be screwed'on 'tothe'screw threadso'n the refiector housing 14. This'cup-shaped memher is centrally perforated andfurnishes-apivotal-support for a hood 26, which is correspondinglyperforatedand at the perforation' is proyided with a turned edge '27 which folds 3 around the edge of the perforationwhich can be easily adjlistedto proper-posiof the cup+shaped member 2'5. soas to fur :nishthe pivotal support. 1 By this means the hood 26' may be adjusted to upright position regardless of the "p osition the cup-shaped member 25 maytake "on account of the matching of the screw threads thereon and desi'red one of acircular series-of holes 30 arranged around the pivotal connecting axis of the hood-26 andcup-shaped member 25, as clear from-Fig? 5; The hood26 is openat the forwardendfa'nd is preferably cut .away: on a slant, as shownin. Fig. 2, to allowthe "convenient placing of eggs therein bythebperat'on who stands in front of the hoodand looks down through a slanting inounted withinthe hood 26 and-is )rovided wlth an annular operating end 3 which registers wit-h the perforations in the hood 26 and the cup-shaped member 25 whenxit is pressedvt'o the dotted line position (Figf y the Pl ing of an egg in'position, these within the reflector is an incandescent bulbthree registering perforations being of suiiicient sizeso that the 'end of an ordinary egg can be pushed partly therethrough, while the wh'ole egg cannot-pass through, as indicated by the-drawing. The switch '35 consists ofkaspring strip of metal-which is proagainst thel-vertical part of the hood 26 by clamps 40, such vertical part of the hood g being cut away so that the clamping tabs 38 post 21 ofthe-cell 16 and thecarbonbi-nding are out-70f contact therewith. Also mounted on this' insulating strip 39 and out of con- "tact with the metal part of the hood 26 is a contact :41 which is engaged by the spring switch 35 when it is pushed to the dotted line position (Fig. 6) but is out of engagement therewith when such switch is in the normal or full line position, to which position it tends to move by its inherent resiliency. If desired, the spring switch 35 may be guided and limited in its movements by a member 42. the contact 41 are provided with connecting wires i l and 43, which are suitably attached in any convenient way, and these wires lead through a hole i5 in the cap 13 to the interior of the casing 10, where a fan-shaped piece of insulation 46 is provided to fit upon the carbon binding post 22 of the cell 17,

from which binding post the wire from the switch 20 is removed. The wire 4A is clamped on this binding post 22 by the clamping screw of such binding post, which clamping screw also holds the fan-shaped piece of insulation in place. This fanshaped piece of insulation is provided with a binding post 47, which is'separated from the binding post 22, and to this binding post 47 are attached :byIa suitable clamping screw both the wire 43 and the wire from the switch 20, the latter of which wires was the one which was normally attached to the binding post 22. The switch 20 and the spring switch 35, are now in series.

When it is .desiredto test an egg, the operator looks down into thehood 26 through the sight tube 31, and places the end of the egg 50 to be tested into the hole in the annular switch operating end 37 of the spring switch 35, pushing it from the full to the dotted line position (Fig. 6) and thereby moving such switch into engagement with the contact 41. The switch 20 having already been closed, this movement of th:

switch 35 closesthe circuit with a lamp 11 which is thereby illuminated; and the light from the lamp 15 shines intoand through the egg, so that the observer looking down throughthe tube 15' and shielded from the directrays of the light may inspect the in terior of such egg and, determine its quality.

Eggs can be tested in this manner very rapidly, and without any visual or nasal discomfort. If desired, in order to prevent accidental breakage of eggs, a cushion 51 may be providedfor the annular member of the switch 35 to bear against when the switch is moved to circuit-closing position,

such cushion also being perforated in registry. with the perforations in the hood 26. If deslred, the perforation in thecushion 51 may be slightly smaller than the other perforations, so that it may act as a cushion directly against the egg itself.

I claim as my invention:

An egg-candling attachment for portable electric lanterns, comprising a screwthreaded member for attachment to a screwthreaded light-containing part of the lan- One of the tabs 38 and tern, a hood pivotally mounted on said screw-threaded member sothat it can be adsired' adjusted position, said spring latch being mounted on one of said two pivotally connected parts and cooperating with a circular series of holes in the other of said parts, said hood andisa-id screw-threaded member beingprovided with an opening to allow the light to enterfthe hood.
